Inflammatory markers (C‐reactive protein, interleukin 1<italic>β</italic>, interleukin 6, interleukin 8, interleukin 10, interleukin 12, and tumor necrosis factor‐<italic>α</italic>) were assayed, and logistic regression analyses were performed to determine associations between inflammatory markers and both baseline cognitive status and subsequent cognitive decline.</p> </sec> <sec id="ijs12001-sec-0004" sec-type="section"> <title>Results</title> <p>There were 243 ischemic stroke patients in the study. In multivariable ordinal logistic regression analysis, age, education, ethnicity, stroke subtype, and interleukin 8 (OR 1·23 CI 1·05–1·44) levels were independently associated with baseline cognitive status. In multivariable logistic regression analyses, age, gender, recurrent strokes, and interleukin 12 (OR 25·02 CI 3·73 to 168·03) were independent predictors of subsequent cognitive decline.</p> </sec> <sec id="ijs12001-sec-0005" sec-type="section"> <title>Conclusions</title> <p>Following ischemic stroke, higher serum interleukin 8 is independently associated with baseline cognitive impairment while higher serum interleukin 12 is associated with subsequent cognitive decline.</p> </sec> </abstract>
